I am 90% sure it was working and belive this is a director issue.. However:
Tested over a VPN and also locally on the LAN and get a line not in service error on the communicator.
Check HQ/Director and foudn that the SG90 @ HQ site is showing the softphone as out of service and is assigned to a MAC address of a device i cant trak (assyume a laptop):
D4-BE-D9-23-A1-EC Headquarters D4-BE-D9-23-A1-EC 172.19.105.163 Unknown Out of Service (Operational) Soft Phone
